Abstract :
A single-chip TV tuner/demodulator IC using a low-IF dual-conversion architecture is implemented. It receives the NTSC/PAL/SECAM signals in the 48 to 860MHz frequency range without off-chip image filters, and performs channel selection, image rejection. and video/sound demodulation digitally. The 6×6mm2 chip in 0.25 μm CMOS with on-chip 75Ω cable driver consumes 1W from a 2.5V supply.
